Galium boreale or northern bedstraw is a species of perennial flowering plant in the family Rubiaceae. It is widespread over the temperate and subarctic regions of Europe, Asia and North America including most of Canada and the northern United States.

Description

G. boreale is a perennial plant that dies back to the ground every winter. Established plants spread by rhizomes, creating colonies of new plants around the original one.

The squarish unbranched stems may grow between 20 centimetres (7.9 in) and 50 centimetres (20 in) tall. The leaves are attached directly to the stem in groups of four; spaced evenly like the spokes of a wheel. Leaves are longer than they are wide and have three prominent veins.

The small white flowers grow in a fairly showy panicles from the top of the stem. Each individual flower has 4 pointed segments that fold back from a fused tube enclosing the stamens and pistil. The lightly perfumed flowers have no calyx. Seeds are formed in pairs in dark fruits that may be covered in short hairs. The Latin specific epithet boreale means northern.

Habitat and distribution

Galium boreale is found in sunny areas with dry to moist soil in forests, shrubs or grassland. It is native to the sub arctic and temperate zones of the Northern Hemisphere. It is listed as endangered in the states of Maryland and Massachusetts.
